Letters Patent No.- 103,890, dated June 7, 1870.

The schedule referred to in than Letters Patent and making part of the same To all whom it may concern Be it known that I, Dnnnrox JonnAsgof Charlestown, in the county of Middlesex and State of Massuch usetts, have invented a new Improvement in Out- ,teis for Wood-Molding Machines; and I- do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked'thereon,-to be a full, clear, and exactdescription of the same, and which said drawings eonstitute part of this specification, and-representin- Figure 1, a side view;

Figure 2, a top view;

Figure 3, a vertical central section;

Figure 4, a side view; and in Figure 5, a central view of the eutter-head, constructed upon the same plan, in order. to form a center cutter. I

This invention relates to the adjustment ot'cut-ters, with special reference to usein the machine patented to A. S. Gear, November 23,1869, the object being to atford a large bearing and positive security to the cutters...

To this end my invention consistsincoustruotinga center spindle, with inclined surfaces upon which the cutters hear, combined with a head with correspondingly inclined surfaces, to set in over' the spindles and. bear upon the outside of the cutters, with a nut arranged to screw into the'head, so as to draw the head down onto the cutters between the inclined surface of faces, a, are formed.

13 is the cutter-head, constructed to pass on over the spindle, and with correspondingly inclined surfaces, as seen in figs. l and 3, and between the .in-

clined surfaces of the spindle and head, cutters (I are placed.

The head is bored out and threaded to receive a nut, G, which passes freely onto the spindle, resting against a shoulder, i, on the spindle, so that,by the turning of the said nut, the head is drawn down, binding the cutters bet-ween the spindle and head.

As a guide for the form which governs the cut, I extend the spindle through the head, as-at D, figs. 1, 2, and 3. y

I By this construction I am enabled to make cutters I which will work to a. centerhy shortening the spindle and extending the cutters until they meet, as seen in figs. 4 and 5, and by this construction I am enabled to hold the cutters more perfectly than by any device yet known.

\Vhile I have described the construction with two cutters, it will be evident to those skilled in the art -that a single cutter may, in like. manner, be secured, or more than two; I therefore do not wish to be understood as confining myself to two cutters.

I claim as my invention 1. The head B; spindle A, with correspondingly inelincd surfaces, and provided with a shoulder, 6-, and combined with the nut O turning into the head B, and

'bearingagainst the shoulder i, so as to secure the cutters bct'ween'the'said inclined surfaces, substantially as described.

2. In a cutter head, consisting of a spindle A, head B, and spindle O, constructed and operated as set forth, the extension of the spindle to form the guide D, as'and for the purpose specified.
